'LEATHER-PUNCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 229,631, dated July 6,1880. Application filed May 17, 1880. (No model.)

To all whom it may concern Be it known that I, RICHARD W. OWEN, residingat Chicago, in the county of Cook and State of Illinois, and a citizenof the United States, have invented a new and useful Improvement inLeather-Punching Machines, of which the following is a fulldescription,reference being had to the accompanying drawings, in which--Figure l is a side elevation. Fig. 2 is an end view Fig. 3, a plan ofthe parts shown; Fig. 4, a detail.

The leading object of this invention is to provide a machine by the useof which holes can be rapidly punched in leather straps and at equaldistances apart. I

The invention consists in combining a hollow punch with thereciprocating bar of a machine constructed substantially like asewingmachine, and with suitable feeding mechanism and a suitable platefor the cutting-edge of the punch to come in contact with; in providingsuch hollow punch with an extension leading into a receptacle, for thepurpose of conveying 2 5 the chips into such receptacle, and inproviding a discharge-tube to carry away the chips.

The machine which I use is, for the most part, constructed like anordinary sewing-machine designed for heavy work, the features 0 whichconstitute my invention being combined therewith. 7

In the drawings, Arepresents the bed-plate. B is a feed-wheel, operatedat intervals by means of the parts a b c, which are moved by 3 5 theshaft 0. These parts are such substantially as are now in use insewing-machines, being enlarged and slightly modified to adapt them tothis work. d is a small roller above the feed-wheel, and supported onthe head D,

0 which head is upon the end of the arm E.

This roller takes the place of a presser-foot, and can be raised whendesired by means of a lever, e. f is aspring which allows this roller clto yield a little.

4 5 g is a bar having a vertical reciprocating movement, correspondingwith the needle-bar of a sewing-machine. h is a hollow punch of suitablesize, secured to the lower end of the bar 9. F is a tube leading fromthe punch to a box or receptacle, G, upon the top of the head D. Asshown, the upper end of this tube Fis connected to the bar g. This tubeF may be regarded as an extension of the punch, and it moves with thepunch. H is a tube leading from the receptacle G to any suitable placefor 5 depositing the chips. This tube H may be flexible.

I is a strap or clip, which passes through holes in the bed-plate andover the arm E, for the purpose of holding the same steady andpreventing vibration, and also for the purpose of allowing the end ofthe arm to be sprung down a little, if necessary. 1; is a guide andgage,.which can be adjusted, by means of the screw 70, for straps ofdifferent widths. m is a spring, which holds the roller 01 down,performing the same office as the spring in common use in connectionwith the presser-foot of a sewing-machine. This roller is supported in asocket, n, and the spring in permits a little vertical movement of thisroller d. v is a brass plate to receive the cutting-edge of the punch inuse.

The bar 9 is operated in the same manner as the needle-bar of asewing-machine.

The operation is as follows: The strap which is to be punched is to beplaced upon the bedplate above the feed-wheel B and beneath the rollerd, with one edge against the guide 2', which is to be suitably adjustedaccording to the width of the strap or other piece to be punched and thedesired position of the holes therein. The feeding devices are to bealso adjusted so that the strap or piece to be punched will be fedforward the proper distance, depending on the distance which the holesare to be apart. Then the machine is to be put into operation the strapor other piece will be fed forward under the punch, and with eachdownward movement of the punch 0 a hole will be made. The chips will beforced up through the tube F, and will be delivered over the top thereofinto the receptacle G, from which they will pass out through the tube H.

I have not described the devices for regulat- 5 ing the feed, nor themeans used for operating the machine, because in these respects themachine is substantially the same as sewing-machines in common use.

The punch is to be secured to the bar 9 in any known suitable manner,and so that it can be readily removed when desired.

Punches of different sizes may be used with the same machine.

I am aware that a solid punch has been used, in connection with a die ina sewing-machine, for the purpose of ornamenting leather, and I do notclaim such construction. Such a machine could not be successfully usedfor punching heavy straps. A solid plate should beprovided to receivethe punch, which should be hollow.

By the use of this machine straps can be punched with great rapidity anduniformity.

What I claim as new, and desire to secure by Letters Patent, is asfollows:

1. A hollow punch, h, in combination with areciprocatiug bar, g, afeed-wheel, B, presser roller or foot (I, and plate 1-, all constructedand operating; substantially as and for the purposes specified.

substantially as and for the purposes specified.

4. ln a punching-machine, a hollow punch provided with a tube orextension, F, to carry away the chips, in combination with areciproeating bar, g, plate v, and areceptacle, G, sub- 3 5 stantiallyas and for the purposes set forth. RICHARD W. OWEN.
